Brief Summary: This study injects a person's own stem cells into heart muscle tissue after a person has one or more heart attacks. The purpose of the study is whether the stem cells will improve a patient's heart performance.

Open or close this module Arms and Interventions
Arms Assigned Interventions
Active Comparator: Low Dose
Patient will undergo biopsy. Skeletal myoblasts will be cultured in growth media.
Biological: MyoCell
Patient will receive injections of cultured, expanded skeletal myoblasts into the myocardium at a dose of 400 x 106 cells.
Active Comparator: High Dose
Patient will undergo biopsy. Skeletal myoblasts will be cultured in growth media.
Biological: MyoCell
Patient will receive injections of cultured, expanded skeletal myoblasts into the myocardium at a dose of 800 x 106 cells.
Placebo Comparator: Control
Patient will undergo biopsy of muscle tissue and biopsy tissue will be sent to lab.
Procedure: Hypothermosol
After the cell culture period of time has passed, patient's myocardium will be injected with the transport media alone. Patient will not receive any cultured myoblasts during these injections.

  2. Age greater than or equal to 18 years but less than or equal to 80 years;
  3. Left ventricular ejection fraction (LVEF) at screening of less than 35% (by multiple gated acquisition scan [MUGA]) as determined by a central reading;
  4. Need or feasibility for revascularization has been ruled out by previous coronary angiogram re-assessed using Dobutamine Stress Echocardiography (DSE) at screening;
  5. Defined region of myocardial dysfunction related to previous MI involving the anterior, lateral, posterior, or inferior walls including the apical septum (excluding the basal septum) assessed by a large area of akinesia in the left ventricle (using DSE at screening).

  16. Hematocrit (HCT) concentration below 30%;
  17. Serum creatinine greater than 2.5 mg/dL (milligrams per deciliter) or end stage renal disease;
  18. Left ventricular mural thrombus;
  19. Known sensitivity to gentamicin sulfate; or severe adverse reaction to nonionic radiocontrast agents;

Active infectious disease and/or known to have tested positive for human immunodeficiency virus (HIV), human t lymphotrophic virus (HTLV), hepatitis B virus (HBV), hepatitis C virus (HCV), cytomegalovirus (CMV); immunoglobulin M [IgM], and/or syphilis. If the panel includes antibodies to the HBV core antigen (HBV-cAg) and hepatitis B surface antigen (HBV-sAg), then an expert will be consulted as to patient's eligibility based on the patient's infectious status;
  21. Exposure to any previous experimental angiogenic therapy and/or myocardial laser therapy, or therapy with another investigational drug within 60 days of screening visit #1 or enrollment in any concurrent study that may confound the results of this study;
  22. Known drug or alcohol dependence or any other factors which will interfere with the study conduct or interpretation of the results or in the opinion of the investigator are not suitable to participate;
